Project Overview

A leading logistics company in Dagenham approached Solar London to reduce their £130,000 annual energy costs. With a 3,500 sqm warehouse roof and high energy consumption, they were the perfect candidate for a large-scale solar installation.

The project involved installing 1,250 high-efficiency solar panels across their warehouse roof, creating one of the largest commercial solar installations in the Barking & Dagenham area.
